3 Claims.

This invention relates to adjustable sighting units, more particularlyto sighting units for use on revolvers or pistols and has for its Objectto provide a sighting bar that has a maximum of angular adjustment withrespect to the bore of the gun with a minimum of actual change in theheight of sights above the bore.

In target shooting, the aiming point desired by most shooters is thebottom edge of the bull" eye, while the desired point of impact is thecenter of the bulls-eye.

Therefore, the distance between the point of impact and the point of aimvaries with the size of bulls-eye required by the rules of difierentmatches at the same shooting distance or at different distances.

The present device provides for meeting the above conditions by allowinga vertical adjustment of the point of aim, without disturbing thehorizontal adjustment, by rocking the sighting unit as a whole on acentral pivot.

The bar on which the sights are mounted serves a diiferent purpose fromthe rib on a shotgun in that it does not, at the moment of proper aim,form any part of the sight picture, being entirely covered by the rearsight. It does however, provide an indication of alignment of hand andgun during a time preceding the final alignment of the sights, a mostshooters bring the gun on to the target in a downward direction makingtheir final sighting alignment at the moment the full bulls-eye appearsabove the sights. This is also the instant of releasing the shot.

The alignment of hand and gun is important because it assures that thefront ight will appear properly in the rear sight notch as the movementproceeds. A further object of the invention is to provide a means toquickly change the vertical adjustment to meet various conditions and atthe same time keep the horizontal adjustment intact, which is of adecided advantage to the shooter.

The graduations on the vertical adjustment screw are designed to permitthe setting of this adjustment at predetermined points located bypractice shooting.

The foregoing and other features of my invention will now be describedin connection with the accompanying drawing forming part of thisspecification in which I have represented my gun sight in its preferredform, after which I shall point out in the claims those features which Ibelieve to be new and of my own invention.

In the drawings:

Figure 1 is a side elevation of a revolver showing my adjustablesighting unit mounted thereon.

Figure 2 is a top view of my device.

Figure 3 is an end view with the revolver partially indicated.

Figure 4 is an enlarged cross-section on line 4-4, Figure 1.

Figure 5 is an enlarged longitudinal section along the line 55, Figure1.

In the carrying out of my invention, I provide a rigid sighting bar I Iwhich carries on the forward end a bead or forward sight l2 and on theopposite end the usual rear sight [3. This bar H is pivoted in thecenter to the gun barrel as shown at 23. It will be readily understoodthat this sighting bar may be varied in its angularity with respect tothe bore of the gun to which it is pivotally connected.

The front and rear sights may be permanently attached to the sightingbar or they may be independently adjustable, vertically or horizontally,or both. After these independent adjustments are made, the sighting beamas a unit may be relatively adjusted angularly with respect to the bore.

The bar I l is provided with a longitudinal slot l4 adapted to ride on asupporting rib I5 permanently attached to the gun barrel I6.

In Figure 1, I have illustrated one of the many types of guns, on whichmy sighting beam may be attached. I do not wish to limit myself however,to this particular type of revolver as the type of gun does not in anyway affect the operation of my sighting unit, as will be readilyunderstood.

The slot l4 may be a close fit to slide on its supporting rib I5 or itmay be relieved as shown in Figure 4, and provision made for adjustmentof the unit horizontally to align the bar with the bore, and for lockingthis adjustment so that the device remains free for quick adjustmentvertically. Such a means is clearly shown in Figure 4 in which thesighting bar H is positioned on the supporting rib 14 by means of thescrews IT.

The teeter of the ighting bar II with respect to the bore may becontrolled or limited by springs 2| as shown or I may use set screws orother means to quickly and definitely locate the sighting bar in itsdesired adjustment.

The fixed rib I5 and pivot support 22 are rigidly attached to the upperportion of the barrel, frame or whatever part of the gun occupies theplace usually occupied by the barrel and frame of a revolver.

I have illustrated a fixed front sight l2 and horizontally adjustablerear sight l3. When the 2,4s4,ses

sight I3 is in proper position it is held thus permanently fixed by lockscrew 3|]. The teetering of the sighting beam II is adjusted byadjusting screw 3| which is locked in position by lock screw 32. Thescrew 3| is threaded in a hole in the sighting bar II and abuts theframe of the gun opposing the action of spring 2| on the opposite end ofthe sighting bar screw 3| turns in a recess in the sighting bar andunder the head of the screw 32 which is provided to lock the screw 3| inits adjusted position. The locking of the screw 3| positions thesighting bar in its vertical angular relation to the bore and may belocked in that position by tightening the screw I7. I do not wish tolimit myself to this method of adjustment as it is in no way essentialto the carrying out of my invention.

While the drawing and description refer specifically to the invention asmounted on a revolver, it will be readily understood that it can beapplied to a pistol or any form of hand gun.

I wish it distinctly understood that my adjustable sighting unit hereindescribed and illustrated is in the form in which I desire to constructit and that changes or variations may be made as may be convenient ordesirable Without departing from the salient features of my inventionand I therefore intend the following claims to cover such modificationsas naturally fall within the lines of invention.

I claim:

1. In a pistol of the class described in combination f rame, a gunbarrel, a sighting unit extending substantially the length of the barreland frame pivotally connected-at-its-central portion to the W T of thebarrel and in vertical alignment with the longitudinal axis' of thebarrel, and carrying a forward and a rear ,sight means to providevertigalangular adjustment of the sighting unit with respebf'to the boreof the gun, whereby when one end of the sighting unitis lowered theopposite end is raised directly above the barrel, and vice versa.

2. In a pistol of the class described in combi- The large head ofnation, a frame, a gun barrel provided with a longitudinal rib aflixedto the top thereof, a sighting bar extending substantially the entirelength of and above the barrel and frame adapted to ride on saidpermanent rib in vertical alignment with the longitudinal axis of thebarrel and carrying a forward and a rear sighting element and centrallypivotally connected to the rib, means to adjust the sighting barvertically and angularly with respect to the barrel so that when theforward sight raises, the rear sight lowers simultaneously in theirrespective positions directly above the barrel, and vice versa.

3. In a pistol of the class described in combination, a frame, a gunbarrel provided with a longitudinal rib aflixed to the top thereof, asighting bar carrying a front and rear sight adapted to ride on thefixed rib in vertical alignment with the longitudinal axis of the barreland extend over the frame and pivoted thereto at substantially itscentral portion, means to adjust the sighting bar angularly with respectto the barrel in a vertical position whereby maximum angular adjustmentis obtained with a minimum of change in the heights of the sights abovethe barrel.
